On Your Success
A man who was discovered unconscious in a shed on his farm is taken by a team. There are signs
of redness and blistering where his clothes are wet, his hands have burns typical of frostbite, and
his clothes are soaked in an unpleasant-smelling liquid. The nurse should be suspicious of being
exposed to
Anhydrous Ammonia
Slow Decompression
Slow decompression, sometimes referred to as gradual or subtle decompression, is a long-term,
gradual drop in cabin pressure. It can be hard to notice before oxygen masks fall or warning
devices go off. Slow decompression may result from:
A faulty door seal
A malfunctioning pressurization system
A cracked window
A leak in the aircraft pressure vessel
A malfunctioning outflow valve
A reduction in cabin air inflow due to a malfunctioning compressor
A failure to cabin pressurization as an aircraft climbs to altitude
Which of the following should be done during slow decompression?
The subtle onset of hypoxia is the main worry when decompressing slowly. The most crucial
thing to do is to use more oxygen.
Epidural hematomas
classically present with abrupt shifts in responsiveness interspersed with brief bursts of clarity.
, A positive inotropic agent should be added in the case of septic shock if fluid resuscitation and
vasopressor administration do not result in a minimum 10% drop in the lactate level.
Positive inotropes
can assist when your heart is unable to pump enough blood to your body due to its weakness.
How do positive inotropes work?
Positive inotropes strengthen the contractions of your heart's muscles, increasing the volume of
blood your heart can pump out and bringing your cardiac output back to normal.
Dopamine
Dopamine treatment during resuscitation is typically saved for hypotension following ROSC or
with symptomatic bradycardia. For the treatment of post-resuscitation shock, dopamine may still
be used in conjunction with other medications, such as dobutamine.
Dobutamine (Dobutrex)
*class*: beta-adrenergic agonist, inotropic
*Indication*: short-term management of heart failure
*Action*: Dobutamine barely affects heart rate, but it has a positive inotropic effect (increases
cardiac output). Stimulates the heart's beta1 receptors.
*Nursing Considerations*:
- Monitor hemodynamics: hypertension, ↑HR, PVCs
- Skin reactions may occur with hypersensitivity
- Beta-blockers may negate the therapeutic effects of dobutamine
- Monitor cardiac output
Vicarious Liability
legal theory that holds one party accountable for the wrongdoings of another.
